ELECTRlC-WIRE INSULATOR.

SPECIFICATION forming part of Letters Patent No. 463355, dated November24, 1891.

Application filed February 28, 1891 Serial No. 3831226. (No model.)

To all whom, it may cancer/t;

Be it known that I, HIRAM F. NEWELL, of Manchester, in the county ofChesterfield and State of Virginia, have invented certain new and usefulImprovements in Insulators for Electric iVires; and I do hereby declarethat the following is a full, clear, and exact description of theinvention, which will enable others skilled in the art to which itappertains to make and use the same, reference being had to theaccompanying drawings, and to the letters of reference marked thereon,which form part of this specification.

This invention relates to certain improvements in insulators forelectric Wires.

The object of the invention is to provide an improved insulatorexceedingly cheap, durable, and simple in Construction, which willfirmly and separately hold several wires Without fastening-wires orother means, will prevent longitudinal movement of the wires, and soconstructed thatthe wires can be easily and quickly attached ordetached.

These obj ects are accomplished by and this invention consists incertain novel features of construction and in combinations of parts morefully and particularly set forth hereinafter.

Referring to the accompanying drawings, Figure 1 is a top plan of theinsulator. Fig. 2 is a side elevation looking in the direction of theleft-hand arrow of Fig. 1. Fig. 3 is a side elevation looking in thedirection of the bottom arrow of Fig. 1. Fig& is a cross-section takenin the plane of line :u x, Fig. 1.

This insulator is preferably formed integral of suitable non-conductingmaterial, and consists of the main or body portion a, preferablycylindrical and dome-shaped or rounded on top, and provided with thehollow base and suitably-forned socket b, by means of which theinsulator is firmly secured on its support. The body at a suitabledistance from its top is provided With a peripheral annular groove d,and beneath said groove, on diametrically-opposite sides, the insulatoris provided with horizontally and laterally projecting portions c c.From the two onter corners of each enlarged lateral portion c arms e eextend up, each arm being provided With a vertical transverse groove ornotch f, extending down from the outer end of its top edge, and with ahorizontal groove or notch g at the lower end of its inner side edge atthe foot of the arm e. Each pair of arms e e is loeated a suitabledistance apart. A pair of downwardly-inclined or overhanging arms orflanges h h are located on diametrically-opposite sides of the insulatorbetween the lateral enlargements and below the horizontal plane of thewire-holding grooves or notches f and g. A wire can be firnly held andsupported by this insulator by resting the same in the top grooves ff ofthe two arms e e on one side of the insulator-body and catching theportion of the wire between said grooves beneath the fiange h on thatside, thereby supporting the wire and firnly holding it againstlongitudinal, lateral, downward, or upward strain. Instead of passingthe Wire through grooves f it can pass through grooves g around thebases of arms e c to and beneath the flange h, or the wire can besecured by having a hitch or loop taken in the same and passed aroundthe bodyso as to rest in groove (Z. It is evident that several wires,either parallel or extending in opposite or different directions, can beseparately supported by this insulator. The lateral arms and grooves sohold the wire that if broken between two poles it will not sag` and dropbetween the other poles. The number of insulators heretofore necessaryis reduced. The supportingarms are stron gly braced and strengthened towithstand the strain and weight of the wires, and the holding groovesand arms are so arranged and formed that the Wires can be easily andquickly secured or removed by the linemen.

hat I claim is- 1. The insulator consisting of the body having` thesocket in its under side and annular groove around its upper portion,the separated grooved arms rigid with the body and extending upwardlybeside the upper portion of the body, and theintermediate downward-1y-proj ecting arms, substantially as described.

2. The insnlator consisting` of the body, arms on opposite sides thereofand rigid therewith and extending up beside the upper portion of thebody and having` wire-holding grooves or notches, and the intermediatedownwardly-projecting arm from the side of the body, substantially asdescribed.

TOO

ing two dianetricaHy-opposte lateral enlargenents, a pair of armsextending up from eaeh enlargement provided with transverse grooves intheir top edges and nner sdes, and downwardly-inelined lateral armsbetween said enlargements, substantiaily as described.

In testinony that I claim the foregoing as my own I affix my signaturein presence of two witnesses.
